Arduino Leonardo (Without Headers)

Overview

The Arduino Leonardo is a microcontroller board based on the ATmega32U4, featuring a 16 MHz clock and 20 digital I/O pins. This specific version (A000052) is supplied without pre-soldered headers, making it ideal for low-profile installations or direct integration into permanent enclosures.

Why Choose This Part

The primary advantage is the native USB communication built into the ATmega32U4, eliminating the need for a secondary USB-to-serial chip. This allows for more flexible USB functionality and a lower total bill of materials in custom applications.

Applications

Getting Started

To begin development, connect the board via USB and use the Arduino IDE, selecting 'Arduino Leonardo' from the board manager. Since this version lacks headers, you will need soldering tools to connect peripherals or interface with breadboards.

Also Consider

Arduino Leonardo with Headers Arduino - Identical functionality but includes pre-soldered female headers for faster breadboard prototyping.

Arduino Uno Rev3 Arduino - The standard AVR platform choice if native USB HID emulation is not required for your project.

Arduino Nano Arduino - A smaller AVR-based alternative that is better suited for direct breadboard mounting.
